摘要:The present invention relates to novel biologically active compounds from fungi of the species Ganoderma pfeifferi DSM 13239, processes for their preparation, and their use. From the fruit body and mycelium of the species Ganoderma pfeifferi DSM 13239, extracts can be obtained which have antimicrobial activity and are suitable as preserving agents, for pharmaceutical and cosmetic preparations, for controlling infections, and for use in fish breeding. Antimicrobially active substances called ganomycins having activity against multiresistant germs are isolated from the extracts. The total synthesis of the ganomycins and their derivatization enables their use an antibiotics.

摘要:The invention relates to a process to increase the concentration of meiosis-activating sterols (MAS) in the cholesterol synthesis wherein potent inhibitors where added, the use of potent inhibitors in the cholesterol synthesis, a pharmaceutical composition comprising the potent inhibitors and the use of the inhibitors for the microbiology production of meiosis-activating sterols (MAS). In the process of the invention the Δ24-reduction or/and 4α-demethylation in the cholesterol synthesis are inhibited. As a result of this inhibition the concentration of FF-MAS and/or T-MAS as meiosis-activating sterols (MAS) are increased.

摘要:The present invention relates to a method of producing vicinal diols from a compound, the method characterised by the step of reacting the compound with a moderately strong acid in the presence one or more reagents capable of supplying hydroxyl groups wherein the moderately strong acid is a strongly reducing agent, but has a conjugate base that is a weak nucleophile. In preferred embodiments the moderately strong acid is hypophosphorous acid and the reagent(s) capable of supplying hydroxyl groups is 2-propanol in water, where 2-propanol is water soluable and organic. This method is particularly applicable to the production of vicinal diols of steroids, including lanosterol. Once vicinal diols of lanosterol diols are formed they are then capable of being further reacted to produce high purity lanosterol.
